vacuum system

[Quickstop [UK]]

I have spent a couple of hours going over the truck and taking out some pretty frayed and perished looking hoses, thinking that I may be getting rid of vaccum leaks etc...

i have found a hose that just disappears under the battery tray and cannot see if there is anything it is supposed to connect to. I gave it a slight tug and it appears unconnected. Is this suposed to be the case?

The connected end goes to a T which goes off to a thin hard plastic tube into the firewall (I think). The other bit goes off to another T which has two connections:

1 goes to the underside of the block with the Syclone logo engraved into it
The other goes off to a unit on the far right hand side of the engine (not sure what it is).

Surely these all can't be open to atmosphere?

Help!

Thanks

Re: vacuum system

ok..so if this were unconnected, what could I expect to happen to the truck and performance?

I have removed the battery and am looking at the tray. Do I need to remove it to reconnect the hose?

As I am standing looking into the front of the truck, the battery is on the left hand side right?

Under there?

Re: vacuum system

Not sure if you can remove battery tray from on top, but I DO know that if you take the wheel liner out you can see the vac ball and where the hose should attach to......hope that helps ya some.

Just cap it off at the T and forget about it. My vacuum ball is taken out completely and everything is fine.

What he said... the vac ball bolts to the bottom of the battery tray

Re: vacuum system

GM put it in for a reason surely? What can I put there instead?

I removed mine and capped off the vac line. I had no problems. It's only there for a vaccuum "reserve" for the cruise and heater/AC controls under boost.

Exactly, I remove my cruise control and my heater controls are sometime slow to switch modes. It will not switch modes with the engine off.
